The Room at the End of the Hall

Wandering the halls of the Library, you realise that you are travelling further than you've ever gone before. The already-tight hallways are becoming claustrophobic, and you feel like you're in some kind of maze. The lights flicker as fear begins to set in. Crashing books, pounding footsteps - you can barely hear either, the sound of your heartbeat overpowering your eardrums.

But then, you stop. There's no danger here; there never was. You slowly realise that this section of the Library has never been seen before, not by mortal eyes at least. You emerge from one hallway to find yourself at a crossroads. A fork between two paths. A door that leads out of the Library, one that would bring you safely to your home. You can already smell a freshly-made meal waiting for you. Or... the door on the right, chained and locked, dusty boards that have been left to rot. Four padlocks holding it all together. You could leave, yes, but you realise it is a test. Will you give up the pursuit of knowledge?

Hello! You have found the end of the scavenger hunt... or have you? In order to access the rest of the content in this article, you'll need to be in four different subscriber groups - some CSS wizardry discovered by the astounding Stormbril (Seriously, go follow him. Stormbril and Cathedris are both absolutely amazing).
And if you have found all four groups, I hope you enjoyed the hunt!

Opening the Door

Four keys, four locks. It doesn't take long to figure out what to do next. But... what could possibly be behind this door? What would warrant this level of secrecy? The door creaks open, almost agonisingly slowly, before you see her sitting there. Saibra, the Ineffable, curator and caretaker of the very Library in which you stand.

Congratulations. You've made it - very few do. This place is a collection of... well, I wouldn't want to call it forbidden knowledge, that would be an oxymoron. But, it is a place where only those most dedicated to learning find themselves. If you are here, that means the very Library invited you in. That is a feat to be very proud of. And, I suppose, it means I owe you somewhat of an explanation.

The Nature of the Library

The Library of Dulūn, the building on the Astral Plane in which all known knowledge resides, is much more than a building. There is the more common knowledge that it exists on a demiplane whose entrance sits in the Astral Sea, but further than that, the Library itself is alive. It was created to house the soul of Myldala's daughter, under the protection and care of Saibra, who created the Library for her to spend the eternity of her afterlife reading and exploring its pages and halls.

Daughter of Myldala

Myldala has many whom she considers to be her children: mages, runesmiths, all who dedicate their lives or time to learning magic. However, she did have one biological mortal child, shortly before the start of the God War. The daughter, Xilethi, looked starkingly like her mother, and people began to take notice. It was not long before the devils found out about her, and she was killed. Her soul, tied to her mother, went to the Astral Sea, a place not meant to be an afterlife. So Myldala enlisted Saibra to give her a home.

The Core Deities

The Core Deities like to claim that they have been around for millenia. However, for some of them, this is not the case. Ehrendil, Khisteus, Conzotl, Tithys, and Lillon have been gods since Sesais split only a few centuries into the creation of the planet - but Maug, Pherynne, Golgash, Syrenna, and Atharon have only existed for a few months. The Devourer, imprisoned in unbreakable chains, copied the actions of Sesais and split himself into fragments, creating the Core Deities of destruction. Since the reversal of the divine switch, caused by Atharon, the new gods have been embedded into history and society, and most don't realise that the god they are worshipping is younger than they are.

The Old Gods

When Atharon reversed the Divine Switch, all celestials who gained their power through the Celestial Plane lost godhood. To the mortals on the planet, it was as though the gods had died - all memories of all of the old gods were erased, and most evidence of their existence was overwritten, with only a few hints of who they once were scattered across the continent and overlooked. However, the gods were not dead. They had not been killed, they had only had their godhood stripped from them. To some, this was akin to death, but to others, it was a chance at a new life. Some, however, decided to try to fight for their divinity, grouping together to discover what had happened and why.

Saibra the Ineffable

Saibra the Ineffable was one of these gods. Formerly known as Ytrix, goddess of riddles, she spent much of her time in her mortal form. She would test mortals on their dedication to learning, their devotion to knowledge. And to those who won against her, she revealed the secrets of the universe.
Saibra is not omnipotent, like many choose to portray her. She simply knows how and where to collect information, and how to piece it together to make it fit. However, she is bound by an oath to Myldala never to interfere with the ventures of mortals, so she remains a silent observer, watching the people of Dulūn in their despairs and in their triumphs.
Even in joining the Cobalt Sun, she still honours this oath. Few mortals have heard her speak - only those who find their way to the Library. Her profession as an Inscriber for her circle requires only recording and writing, something that she has always enjoys. And she remains silent on the mysteries of the world.
